Microbial whole-genome sequencing is an important tool for mapping genomes of novel organisms, finishing genomes of known organisms, or comparing genomes across multiple samples. Sequencing entire bacterial, viral, and other microbial genomes is important for generating accurate reference genomes, for microbial identification, and for other comparative genomic studies.
Unlike capillary sequencing or PCR-based approaches, next-generation sequencing (NGS) allows microbiology researchers to sequence hundreds of organisms with the power of multiplexing. Unlike traditional methods, NGS-based microbial genome sequencing doesn’t rely on labor-intensive cloning steps, saving time and simplifying the workflow. NGS can identify low-frequency variants and genome rearrangements that may be missed or are too expensive to identify using other methods.
De novo whole-genome sequencing involves assembling a genome without the use of a genomic reference and is often used to sequence novel microbial genomes. Illumina sequencers provide unparalleled raw read accuracy, read length and read depth for high-quality draft and complete microbial genome assemblies.
Microbial whole-genome resequencing involves sequencing the entire genome of a bacteria, virus, or other microbe, and comparing the sequence to that of a known reference. Generating rapid and accurate microbial genome sequence information is critical for detecting low frequency mutations, finding key deletions and insertions, and discovering other genetic changes among microbial strains.
